Hi, Im trying to use this BM

CASE
WHEN MONTH(Cycle)='10' THEN

(sum($ New Annual Salary(in USD))/ sum($ Annual Salary(in USD)))-1 ELSE sum($ New Annual Salary(custom)(in USD))/ sum($ Annual Salary(in USD))-1 end

and its sucessful but in the Grand Total I requiered an average not a sum, and usually I can use the agregation option per column but in this especific one, I can´t, if I skip the sum in the calculation, the result is incorrect the only thing I need to get an average is in the Grand Total

    @Pam1324 Since the only difference between the calculations for Month 10 calculation and all other months is the numerator, the grand total will work more cleanly with the case statement inside the first sum like below. Aggregations work best when they are outside of the case statement, rather than inside them.

    sum(case when month(`cycle`) = '10' then `$ new Annual Salary(in USD)` else `$ New Annual Salary(custom)(in USD)` end) / sum(`$ Annual Salary(in USD)`) - 1
